0–100, higher is better. How it is calculated

Helion is a technology company focused on developing the world's first fusion power plant, aiming to create a new era of plentiful, zero-carbon electricity. The company positions itself as an innovator in the energy sector, targeting a broad audience including potential employees, investors, and energy stakeholders. Their website reflects a professional and modern digital presence, leveraging WordPress CMS with integrations such as Google Analytics and Cookiebot for privacy compliance. The site is well-structured, mobile-optimized, and provides clear navigation and content relevant to their mission and services. Security posture is strong with HTTPS enforced and cookie consent mechanisms in place, though some security headers and explicit policies could be improved. The absence of WHOIS data for the domain introduces some uncertainty about domain registration transparency, but the overall website professionalism and compliance suggest a legitimate operation. Strategic recommendations include enhancing security headers, publishing a security policy, and providing incident response contacts to strengthen trust and compliance.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

4 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Helion operates in the energy sector with a focus on fusion technology, a cutting-edge and highly specialized market. Their business model revolves around technology development and commercialization of fusion power plants. The company appears medium-sized with a founding date of 2015, though domain registration data is unavailable. They maintain active social media channels and provide career opportunities, indicating growth and talent acquisition focus. The website content and structure support their market positioning as a technology innovator. No direct partnerships or subsidiaries were identified from the website content. Revenue streams likely include technology licensing, partnerships, and possibly government or private funding. The company demonstrates strong branding consistency and trust signals through professional design and privacy compliance.

Security posture

The website employs HTTPS and a comprehensive cookie consent mechanism via Cookiebot, indicating good privacy compliance and user data protection practices. However, no explicit security policy or incident response information is published, which is a gap in transparency and readiness. Security headers are not detected in the provided data, suggesting room for improvement in hardening the web server against common attacks. No vulnerabilities or exposed sensitive data were found in the HTML content. The use of up-to-date WordPress and modern libraries suggests reasonable maintenance. Overall, the security posture is good but could be enhanced by publishing security policies, adding security headers, and providing clear incident response contacts.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a dedicated security policy page outlining security practices and compliance.
  3. Provide clear incident response contact information (e.g., security@ or abuse@ email addresses).
  4. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Regularly audit and update third-party libraries and plugins to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on WordPress 6.8.1, utilizing Bootstrap for responsive design and several JavaScript libraries including jQuery, AOS for animations, Swiper for sliders, and Ionicons for icons. Google Analytics and Google Tag Manager are used for analytics and marketing tracking. Cookiebot manages cookie consent, ensuring GDPR compliance. The site loads multimedia content such as videos and high-resolution images, indicating moderate performance. Mobile optimization is good with responsive design elements. Accessibility is basic but present. No hosting provider information was detected. The technical stack is modern and well-maintained, though performance could be further optimized by leveraging caching and CDN services if not already in place.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
